Apple just released the third version of the iOS 12 beta as part of the public beta program. It means that everyone can now install a development build of iOS 12, the next major version of the operating system for iPhone and iPad.

Don’t forget this is still a beta version. Things will crash, things won’t work. Don’t be surprised if you lose data in your Photos, Notes or Messages apps for instance.

But if you have an iPhone or iPad that you don’t use every day, you can get a glimpse of the future of iOS right now. While the final version of iOS 12 should be released near the end of September, Apple is going to release beta versions every few weeks over the summer.

Before installing the beta, don’t forget to back up your device to iCloud and/or your computer using iTunes. You can then head over to Apple’s beta website, sign up with your Apple ID and download the beta profile.

The profile is just a tiny file that tells your iPhone to check for public betas. After restarting your device, you can open the Settings app and install the iOS update just like any normal software update. If you already installed a previous beta, it’s time to update.

In September, your device should automatically update to the final version of iOS 12 and you’ll be able to delete the configuration profile.

Here’s a quick rundown of what’s new in iOS 12. The main feature of iOS 12 is a performance improvement, especially for older devices. If you have an iPhone 6 or an iPad Air for instance, you should see a big improvement when it comes to launching apps, triggering the camera and entering text.

The other big theme of the year is new features to help you spend less time using your phone. There’s a new Screen Time feature to see and control how much time you spend using each app. Notifications are now grouped and you can silence them from the lock screen. You also can turn on Do Not Disturb when you’re in a meeting, for a few hours or for longer.

Apple didn’t stop there, and added new power features as well. Developers will be able to take advantage of a new file format for augmented reality and new features in ARKit 2.0. Apple is releasing the Workflow app as a new Siri Shortcuts app. Developers will be able to add information to Siri, as well, so that you can add a boarding pass or a music playlist to Siri.

The Photos, News and Stocks apps have been improved, as well as Apple Books (the app formerly known as iBooks). Apple is introducing Memoji on the iPhone X. It’s a customized avatar that you can use in iMessage and FaceTime to represent you.
